Cst of phenol water system
WebFor example, the system triethylamine-water has an LCST of 19 °C, so that these two substances are miscible in all proportions below 19 °C but not at higher temperatures. The nicotine-water system has an LCST of 61 °C, and also a UCST of 210 °C at pressures high enough for liquid water to exist at that temperature. The components are ... WebThe given statement is true. The phenol-water system has a upper critical solution temperature. Above this temperature, the components of phenol-water system are miscible in all proportions. The upper critical solution temperature is an upper limit to a temperature range of partial miscibility, or miscibility for certain compositions only.
